Abstract
A threaded coupling for ensuring a complete connection between fluid conduits includes a body portion of a fluid conduit, an axially forward sealing surface, a thread, and an interference member. The interference member is disposed on the body portion and is engageable with a portion of another fluid conduit to apply a load on the interference member when the fluid conduits are threadably connected together. The interference member is configured to prevent a complete sealing engagement between the fluid conduits when the load on the interference member is less than a predefined amount, and is configured to allow the complete sealing engagement between the fluid conduits when the load on the interference member meets or exceeds the predetermined amount.
